  title: Kubernetes Autoscaling RBAC API
  description: The Kubernetes API lets you query and manipulate the state of objects in Kubernetes. The core of Kubernetes control plane is the API server and the HTTP API that it exposes. Users, the different parts of your cluster, and external components all communicate with one another through the API server. The API is a resource-based (RESTful) programmatic interface provided via HTTP that supports retrieving, creating, updating, and deleting primary resources via the standard HTTP verbs (POST, PUT, PATCH, DELETE, GET).
